Explanation:

• For the first question, a star is a massive ball of hot gas that emits its own light. Planets orbit stars and reflect light, comets have a nucleus with a tail when near the sun (not shining by their own light in the same sense as stars), and the moon is a natural satellite that reflects light from the sun.
• For the second question, stars produce heat and light through nuclear fusion (not spontaneous explosions). Nuclear fusion is the process where hydrogen atoms combine to form helium, releasing energy.

Answer:

First question: Star
Second question: False
